It's Monday morning and we have just one week before the start of the Oregon Legislature's 2013 session. So it's no surprise that this weekend featured a lot of advance looks at the session, from issues affecting public-employee unions to motorists who use studded tires.

PERS INVESTMENTS: While we're on the subject of pensions, The Oregonian's Ted Sickinger reports that the state's pension fund had a strong year in 2012, with returns up 14 percent. That reduces the size of the unfunded liability from just over $16 billion to $14 billion.

IMMIGRATION: Peter Wong of the Salem Statesman Journal looks at immigration issues in the upcoming session, particularly a bill to allow in-state college tuition to all residents, regardless of their immigration status.

STUDDED TIRES: Two bills filed for the upcoming session would place a fee on studded tires to help offset the damage they do to roads, the Statesman Journal reports. Another bill would require a permit to use studded tires.

MARIJUANA IN OREGON: An official from the Marijuana Policy Project,
which played a key role in passage of Colorado's legalization measure,
told Oregon pot activists Sunday that they should be aiming for a 2016 initiative
here. He said it's better to wait to have the marijuana issue on the ballot in a
presidential year when turnout will be higher, The Oregonian reports.
Rep. Earl Blumenauer, D-Ore., also attended the meeting and said he
supported easing federal prohibitions against marijuana.
